Reducing Tee Dimensions
A reducing tee branches a smaller line off a larger run in one fitting. It is the normal way to take a service connection, instrument line, or lateral off a header without fabricating a reinforced branch.
Sizing convention.
Reducing tees are called out run × run × branch, commonly shortened to run × branch. A 6 × 4 tee has a 6" run and a 4" branch. The tables carry outside diameter, inside diameter, and wall thickness for both the run and the branch, plus the R and B center-to-end dimensions.
Why not a weldolet.
A reducing tee is a wrought fitting to ASME B16.9 with a defined rating and a full-penetration circumferential weld at each end. A branch fitting is a good answer when the branch is far smaller than the header, but at moderate size ratios the tee is the simpler part to specify, inspect, and defend.

Common Questions
How do you specify a reducing tee?
Run size, run size, then branch size, usually written run × branch in practice. A 6 × 4 reducing tee has a 6" run with a 4" branch outlet. Give the schedule and material grade for each end when you request a quote.
How small a branch can a reducing tee have?
Standard reducing tees cover a wide but finite set of run and branch combinations, and the tables above list the ones made to the standard. Once the branch gets very small relative to the run, a branch outlet fitting is usually the more practical answer.
What are the R and B dimensions?
They are the center-to-end dimensions for the run and the branch, measured from the intersection of the centerlines to each welding face. Both are listed by size and schedule in the tables above.
